I recently received some leather items. A sheepskin brown and black jacket with a hood, a sheepskin black jacket, and a calf backpack. I've looked at the various ways to tell if something is leather but I'm the type that won't be convinced unless an expert sees it. Below are pictures of the items if anyone would like to give their opinion. The first picture is the brown and black hooded jacket. The next three is the sleeve of the regular black jacket. The rest of the pictures are of the backpack.
